POTABILIZATION OF CLYPOT AND GAURAIN QUARRY WATER
In the Clypot quarry, in Belgium, located in an area with high water stress, we entered into a contract with the local authority to recover the quarry water and redirect it into the public distribution network, after its potabilization. The wastewater treatment process involves both the elimination of solid parts and unwanted chemical elements such as iron or manganese and specific controls to ensure their bacteriological quality.
During 2024 the Group continued the recovery of quarry water to supply the public distribution network (Société Wallonie des Eaux - SWDE). The volume of Clypot quarry water sent for potabilization was 1,499 thousand m³ (compared to 1,309 thousand m³ in 2023).
Cementir also began supplying quarry water from the old Gaurain quarry, totaling 139 thousand m³. The target is to reach 1,700 thousand m³ from Gaurain. The Group invested to maximize the supply, aiming for a total of around 4,000 thousand m³. These operations enable the recovery of quarry water into the public distribution network, optimizing the management of quarry water levels. At the same time, they significantly reduce the local authority's reliance on well water, particularly in the Gaurain and Clypot districts, which are areas of extreme water stress.
